Rocky Mountain Metro Airport to Mcnary Field BJC → SLE
846 nautical miles (973 statute miles) northwest on a straight line, true course 297°, about 288° magnetic at the departure end (variation 9E). At 120 knots that is 7 h 07 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 7:11 am PDT (14:11 UTC), after sunset at the destination. Right now BJC is VFR, wind from the south (170°) at 6 knots; SLE is VFR, wind calm. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 1 flights in the DOT's last twelve reported months, the route's page.

- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the first 239 nm of the route.
- AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 10 to 189 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 90 to 487 nm out.
- AIRMET TANGO 5W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 129 to 189 nm out.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 139 to 497 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the route from 438 to 577 nm out.

- AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 667 to 736 nm out.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from BJC.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 6 forecast points nearest it (DEN, RKS, PIH, BOI, RDM, PDX). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
